"Our core values as a brand center around treating people with respect, and we have taken this situation very seriously. As soon as we learned what had occurred, we investigated and took swift action. The two employees who were involved are no longer employed by Wendy's. We also have reached out and have formally apologized to the customer," Wendy's spokeswoman Candis Goins said.

On Tuesday, about a dozen people protested outside the Wendy's to voice their frustration. Wendy's apologized to the family, but the family said it won't accept it until their children are formally apologized to.

"While I do understand that two individuals were responsible for this, there's a systemic problem that this isn't addressed to the people it hurt," Oswoski said.
